NITED STATES LATENT OFFICE.

REMOVABLE SEAT.

SPECIFICATION forming part of Letters Patent No. 554,720, dated February 18,1896.

Application filed October 9, 1895.

To all whom it may concern:

Be it known that I, JEREMIAH OMEARA, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Removable Seats for Chairs, &c., of which the following is a full, clear, and exact description.

This invention is in the nature of an improvement upon the invention forming the subject of my United States Patent No. 541,005, granted June 11, 1895.

The invention consists, first, in a retaining device for securing the interchangeable seats within the seat-frame, such seats being reversible if desired.

The invention further consists in a hatreceiver for use in connection with theaterchairs in which my interchangeable seats are employed.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a bottom plan view. Fig. 2 is a cross-section taken in the plane of line 2 2, Fig. 1. Fig. 3 is a cross-section taken in the plane of line 3 3, Figs. 1 and 2. Fig. 4 is a bottom plan view of a modification. Fig. 5 is a crosssection taken in the plane of line 5 5, Fig. 4; and Fig. 6 is a cross-section taken in the plane of line 6 6, Figs. 4 and 5. Fig. 7 is a perspective view of the retaining device. Fig. 8 is a bottom plan view of the theater-chair seat. Fig. 9 is a side elevation thereof; and Fig. 10 is a cross-section taken in the plane of line 10 10, Fig. 8.

In Figs. 1, 2, and 3 the bevel of the seatframe a and of the seat bis made to converge upwardly from the bottom, so as to provide for the insertion of the seat from the bottom. The seat is secured in position by means of any suitable number of retaining devices, each of which comprises a flat plate of metal 0, secured to the frame by a pivot-screw d and having the set-screws or adj usting-screws e f at opposite ends. Any number of these retaining devices may be employed, but ordinarily two, arranged opposite one another, will be sufficient. The retaining devices are pivoted in place first in order to prevent their accidental loss by displacement, and also to provide for the rotation of their plates into Serial No. 565,115. (No model.)

planes that will clear the path of the seat in the insertion and removal of the latter. In order to adapt the retaining devices to chairs of different sizes, and such as are designed to receive persons of different age or weight, I prefer to make the screws 6 and f of difierent strength or diameter. The smaller screw will be used for the seat of a childs chair, while for the seat of a chair for an adult the larger screw will be used. The strain is on the screw that holds the seat in place. One or two sizes of retaining devices, therefore, only are necessary for all or very many varieties of chairs. The screws, as e, which engage the seat proper may enter holes in the seat prepared for them, which holes may be bushed or reinforced, if desired, in order to prevent the displacement of the retaining devices.

As shown in Figs. 4, 5, and 6, the bevel of the seat-frame and seat may converge downwardly to provide for the insertion and removal of the seat from above, and in that case the set-screws of the retaining devices may enter holes in the seat-frame.

The use of the two screws in each retaining device admits of compensation for a loose fit, in addition to the adaptability of one or a very few sizes of retaining devices to all sorts and kinds of chairs.

In Figs. 8, 9, and 10 I have shown my invention as applied to a theater or opera chair in which the seat is reversible, one side being covered with cane or other material or substance suitable for use in summer and the other side being upholstered in suitable manner for use in Winter. As indicated in Fig. 10, these two surfaces may be made upon independent frames united by screws or other means, or, obviously, a single frame may be provided having its opposite sides covered with different fabrics or materials. In this reversible seat it will be advisable to provide for the ventilation of the interior of the seat. For this purpose the seat-frame and the frame of the chair will be provided with registering openings g.

Inasmuch as both sides of the theater or opera chair are upholstered or finished, provision must be made for taking the point of the fastening-screws, and to this end I may provide wear-plates h, provided with holes or Y countersinks into which the points of the screws enter, so as to prevent displacement, the said wear-plates being arranged between the points of the screws and the adjacent upholstered surface of the chair-seat.

The pivot screws or devices d of the retaining devices may be utilized to receive the ends of a curved-wire hat receiver or support 1', constructed and arranged substantially as shown.

Obviously the invention is applicable to chairs of various sorts, settees, sofas,and other articles of furniture wherein it is desirable to have a removable, interchangeable, or reversible surface, and I mean to include such use of my invention in the claims herein.

lVhat I claim is 1. A removable or interchangeable chairseat, and a supporting or surrounding frame therefor, the adjacent edges of which seat and frame are complementally beveled, combined with the seat-retaining device, herein shown and described, comprising the plate a pivoted between its ends and provided with the set screws 6 and f of different sizes and bearing upon the seat and the frame respectively, substantially as set forth.

2. A removable or interchangeable chairseat and a supporting-frame therefor, combined with pivoted seat-retaining devices, and a hat receiver or support having its ends secured by the pivots 0f the seat-retaining device, substantially as described.

In testimony whereof I have hereunto set my hand this 8th day of October, A. D. 1895.
